TIE-PLATE AND CLAMP.

Specification of Letters Patent.

Patented Nov. 15, 1921.

Application filed May 11, 1921. Serial No. 468,672.

To all whom it may concern:

Be it known that I, GRANVILLE ADAMS, a citizen of the United States, anda resident of Hamilton, in the county of Butler and State of Ohio, haveinvented certain new and useful Improvements in Tie-Plates and Clamps,of which the following is a full,

. clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

My invention relates to tie plates and clamps for railroad practice. I

In. the past, so far as I am advised, tie plates for use in laying railshave been merely flat plates with the spikes therein engaging over thebase of the rail, tolhold it down. In such construction the failure ofspikes on the inside or outside of any tie plate will permit the rail toshift in the direction in which the spikes are gone. Also in relayingrails there is always a chance of spreading until the rails are fullyspiked down, thereby increasing considerably the time required to relayrails over a busy track, since a good sized crew must busy itself witheach rail to get the old one out and the new one in, between trains.This applies also to replacing of ties.

The object of my invention is to provide a tie plate combined with aclamp which will" hold a rail firmly to a tie so long as the tie plateis not free to shift and when used at joints between rails will hold thejoints against spreading or the rails from shifting lengthwise. Usuallyonly one of such clamps is needed to prevent shifting of a rail, but inwhen laid;

turn tables, scales, and the like, it is my ob ject to prevent shiftingin any direction of the rails by use of my plates with clamps on bothends thereof.

These objects I accomplish by that certain construction and arrangementof parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 is a perspective view of the tie plate and clamp assembled overa rail, which is merely dotted in;

Fig. 2 is aperspective view on a larger scale of the clam member for thelefthand side of the tie p ate.

The tie late is made up of a base 1 on which the ase 2 of a rail willrest. At the inside of this base (i. e. the inside of the track are theusual holes 3, 3, for spikes 4, (dotted 1 At a point where the outerside of the rail flange will rest is formed a shoulder 5 which acts asan abutment for the rail base. From this shoulder the body of the plateslopes down to the outer web 6 thereof, which is tapered off at the endsas at 7, 8, and pro vided with a series of holes 9 at each end for usewith a stop pin. The main portion of the base also tapers as at 7, 8, tomeet the tapers 7 and 8 at a point.

The clamps, of which a left side clamp only is shown, are made up with abase 10 and two hooked shaped ends 11 and 12. The base has a surface 18on which rests the base of the rail, and a cut-out portion 14 whichpasses under the tapered end of the tie plate.

he hook 11 is shaped to engage firmly over the base of the rail on theinside, and the hook 12 is shaped with a tapered side wall 15. The sidewall of the cut-out portion is also tapered as at 16, so thatthe clampcan be hooked under a rail and driven over the pointed end of the tieplate to make a firm fit when driven home.

The outside spike hole, of which there need be but one, is formed in theshoulder portion as at 17.

As so constructed the tie plate will need be used ordinaril on everythird or fourth tie and is spi ed down together with the rail and thenthe clamp driven into place and locked there by means of a cotter pin orother stop pin dropped in one of the holes 9.

The rail cannot creep with relation to the tie plate because it isfirmly wedged against it by the clamp and the looseness of the spikeswill not permit the rail to rise from the tie plate.

In relaying rails a crew can proceed by removing the inside spikes,knocking oil the clamps, removing the old rail and resettingthe newrail. A gang of two men can then follow along and replace and drive upthe clamps, thereby holding the new rails in perfectly safe conditiontemporarily, without driving a single spike. One of the tie plates withclamps at both ends will hold two rails together without permitting anyparting or creeping and without the use of any spikes.

In replacing ties, the spikes can be pulled and the tie slipped outwithout affecting the relation of the tie plate, clamp and rail, sincethe clamp will hold the tie plate on the rail. M

In general, my device makes for greater security of rails on tiesagainst lifting, creeping, parting, turning out, or spreadin Having thusdescribed my invention, what I claim as new and desire to secure by Letters Patent, is

' 1. In a tie plate and clamp, the combination with a plate for mountingon a railroad tie to form a base against which a rail will rest, atapered end to said plate extending lengthwise of a rail to be mountedon the plate, and a clamp adapted to engage said tapered end, and thebase of a rail at a point removed from the said plate, for the purposedescribed.

2. In a tie plate and clamp, the combination with a plate for mountingon a railroad tie to form a base against which a rail Will rest, ashoulder on the plate against which one side of the rail base will abut,and an independent elamp'adapted for engaging the rail base at a pointremoved from the plate and also engaging the plate to hold the rail baseup against said shoulder.

3. In a tie plate and clamp, the combination with a plate for mountingon a railroad tie to form a base against which a rail will rest, ashoulder on the plate against which one side of the rail base will abut,a tapered end to said plate, and a'clamp adapted to be driven over saidtapered end and to engage the rail.

4:. A tie plate comprising a base for a rail having a hole or holestherein for spikes,

a shoulder for a rail base abutment, a hole or holes adjacent theshoulder for additional spikes, a tapered Wing on one side of the plate,and a clamp having aportion to fit under and hook over the base of arail lying on the plate, and a portion to lit under and hook over a wingon the plate, said last noted portion being shaped in tapered form topermit driving onto the said tapered wing.

5. A tie plate comprising a base for a rail having a. hole or holestherein for spikes, ashoulder for a rail base abutment, a hole or holesadj aeent the shoulder for additional spikes, a tapered wing on at leastone side of the plate, and a clamp having a portion to fit under andhook over the base of a rail lying on the plate, and a portion to fitunder and hook over a wing on the plate, said last noted portion beingshaped in tapered form to permit driving onto the said tapered wing, anda stop pin for said clamp, said. plate having a plurality of openingsthere in in which to place the stop pin.

6. In a tie plate and clamp, the (l1'll)lI]:\- tion of a tie platehaving a rail abutment on the outer side thereof, and a clamp adapted tohook around the inner side of the base of a rail resting on the plateand around the outer side of the plate as well, for the pur posedescribed.
